How Do I connect my 13" Macbook to a larger monitor?

Hi, I work a lot in Ableton Live and the whole program feels kind of cramped on a 13" screen. So I was thinking about hooking it up to a 17" Dell monitor I have.

I've googled it but it seems like there are many different types of connections depending on what model your monitor is. I wanted to make sure I was buying the correct wires, hopefully you guys can help me.
